A CGRPORATION OF DELAWARE.

TYPENRITIZ-IG MACHINE.

Application filed November 12, 1925. Serial No. 68,553.

This invention. relates to a web-typing machine of the well-known Underwood type. In said machine. longitudinally. fan-folded web interleaved. with carbons, and. is inserted around the platen of the machine to be typed upon. After typing each form, the platen is elevated to straighten out the web and the carbons are shifted to be presented to a fresh form. Then the platen is lowered I again to its typing position to tear off the tends far back from the platen. which is another source of creeping of the plies and trouble with reg1strat1on. 7

In th1s invention, there provided a of the carbon-carrier, the slitting truck be ing automatically controlled during the platen elevating and lowering operations. The truck is reciprocable towards and away from the platen between the carbon-carrier and the platen itself. It is connectible tothe platen-frame, so that, when theplaten elevated, the truck need not move, but, when the platen is lowered, the truck will be driven to the rear of the machine away from the platen, slitting the folds of web. The connection between the elevated plateu and the splitter truck is effective during the swing of'the platen down to typing position, to thrust back the splitter truck automatically. I

There may be a relative adjustment such that the carbon-carrier may pick up the splitter truck at any selected point, this adjustment co-operating with the adjustable rear stop for the carbon-carrier, so as to accon'nnodate a variety'of work.

Other features and advantages will hereinafter appear.

According to the method of handling the work in this invention, a multi-ply longitudinally fan-foldedweb 10 is threaded between carbons 11, which are mounted upon carbonblades 12, and the leading edges of both the 86 carbons and the Web are squared so as to form a. pack, which is inserted down a rear table 13 and under a platen 14, which 00- operates with feed-rolls 15 to line-space the web. Then the platen is rotated to position 00 the web for the first line of typing on the first form, and other lines are typed on the form by means of type-bars 16, the platen being subsequently elevated to straighten out the web and to gage 1t to form length against 95 a front gage 17. The end of the web is held against the gage while the carbon-carrier is moved back by means of a handle 18, thereby presenting the carbons to a fresh form of the web. I

In order that the plies of the web may be separated before being inserted around the platen. there is provided a slitting truck,

rocate on'rails mounted on the platenframe of the machine. Upon said plate there is provided a series of knives 21, preferably mounted on studs 22, the knives being thread- 5 ed between the plies of the web in a manner to afford the splitting or slittingof the plies when the truck is moved backwardly. Said knives arelateral-ly adjustable to accommodate difierent widths of webs, and are ar- 10 ranged to be locked in different positions along rails 23, which may be fastened to the plate 19. p After finishing the typing of a form, the platen is elevated to permit stripping of the carbons, and is again lowered to typing posh tion, and at this manipulation of the platen it is desired to operate the slitting truck 1116-.

chanically. To this end, there is provided mechanism which may include a tube 2% and 29 a shaft telescopically mountedin said tube.

The forward end of the shaft may be pivotally mounted at 26 on a plate 27, which is fast to one of the end plates 28 of the platenframe. The tube or guide is pivotally 2 mounted at 29 on an upwardly-extending bracket 30 forming an plate 19.

Referring-to Figure 5, in which the 'ext reme forward position of the slitting truck integral part of the is shown, it will be noted that at the end of the tube 2e there is provided a pawl 31 mounted on said tube and engaging with a notch 32 at theend of the shaft 25.

In Figure 6, the platen is shown in its 3 midway position while being swung downtruck with it to slit the plies of the web.

In Figure 7, the platen is shown in its normal position, in which a lower extension 36 ofv the pawl 34 engages with a pin 37, which is mounted on a plate 38 fast on one of the rails 20, and, owing to the interference of said pin 37, said pawl is rocked on a pivot 39, thereby releasing the end of the shaft which collapses further into the tube.

In Figure 9, a cross-sectional view is shown of the pawl, the tube and the shaft. and it also shows asliding block 10 for supporting the pawl and the interfering pin for releasing. thesame. This view is self-explanatory and shows only one form of the invention, it being understood that any other form would be suitableprovided the pawl was made slidable and settable on the tube. The pawl is held in its normal position by means o a spring 41.v

In the Underwood fan-fold biller, has

51 are tightened to lock the knive been customary to provide means whereby the web and the carbons can be withdrawn from the machine, so that another web hat i s other types of forms printed thereon be used. This being an excellent feature of I said machine. it is not desired to destroy it 1. a 11' 1 1'14. t L Q t \n 7) he use or taesn. tin much as stpaime unit. To this end, there is provided mechrying truck 42. pair of pins d3 entering holes in the truck slotted for engagement w 19 the pins ant hers 4A laivotally'mounted at if) on said truck l2. In this manner it will be seenthat it IS an easy matter to withdraw the web l y simply releasing the locking members and withdrawing the plate upon which. the res ar mounted. The carbon-carrier is mounted on a truck 46 in a similar manner, the clamping elements being similarly numbered for easy identification. Both the carbon-carrying truck 46 and the slitting truck 42 are provided with wheeled? designed to roll on the rails 20. The wheels are revolubly mounted on frames l8, which frames are secured beneath the trucks by means of rivets all.

In order that the knives may be individually threaded between the plies of the web, and in order that the knives maybe positioned to accommodate webs of different widths, the knives are pivotally mounted on the studs 22, which are provided with square heads 50 designed to slide between the rails 23. The knives may be individually swung into or out of engagement with the web, and may be locked in either position by means of finger-pieces 51. In order that the knivc may be held at the proper angle when sw to their effective positions, there may be provided an angular plate 52 which serves a backing for the knives. Said plate 52 is designed to slide between the rails 23 and n be locked in position when the linger-piece,

hen lowering the platen to normal posi ion, the web" is wrapped therearound, thereby drawing on the web ant its associated carbons, but, since the slitting truck is moved rearwardly while the web is pulled forwar ly, it will be seen that the slitting tr cl; does need to travel the full length or" a form, considerably less travel being enough to completely slit the form. For clearness, in il-.istrating this condition, a stop-gage is shown, which co-operate's with the carbon-carrier to limit its travel, said gage being shown in r ,g tires 5 and 7, the latter showing the carl'ioncarrier moved forwardly away from the age.

Means are also provided inthis inven on for laterally guiding the web to tie said means 'ncluding a pa'" of side 5 adjustably mounted upon across-rod and a second pair of gages 56 adjnstably mounted on blocks 57 to which the blades are secured.
